Patented June 20, 1933 PATENT OFFICE WALLACE A. FREELAND, OF BOISE,IDAHO ADVERTISING DEVICE Application filed May 8, 1930. Serial No.450,689.

This invention relates to advertising devices and more particularly tothat type of device which is used to attract the attention of apasser-by to a window display.

An object of the invention is to provide an advertising device whichwill .throw a continual changing design of multi-colors upon a frostedglass to attract attention of the passer-by.

Another object of the invention is to provide a device of this characterwhich may be easily installed in a shop window or the like and in whichit is only necessary to hook up the device to a source of electricalsupply to cause the same to operate and in which the operation of thedevice will be continuous without the care of an attendant.

Another object of the invention is to provide an advertising deviceconsisting of a tube like member closed at the front end with a frostedglass and a rotating compartment in the ward the frosted pane of glassin which colored pieces of glass or celluloid may be placed and a systemof mirrors in front of the compartment and a light in the rear of thesame so that the light passing through the compartment will cause thereflection of the colored pieces of glass or celluloid to be cast uponthe frosted pane of glass, the sameacting as a screen on which the imageis PIOJBCted and thus attract. the attention of the passer-by.

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawing in which- Fig. 1 is a top plan view of in improveddevice assembled with suitable driving mechanism.

Fig. 2 is a longitudinal sectional view taken substantially on line 2-2of Fig. 1

Fig. 3 is a transverse sectional view taken on line 33 of Fig.2.

Fig. 4 is a similar view taken on line 44 of Fig. 2. v I

Referring now to the drawing wherein like reference characters designatelike parts throughout the-several views, the device comprises a hollowcylindrical member 1 mounted upon a base 2 and secured thereto bymeansof the bracket 3. The tube 1, as seen in Fig.

2, is flared outwardly near its'forward end as indicated at 4 and isprovided at the extreme outer end with a groove 5 for receiving acirclip 6 for retaining'a frosted pane of glass 7 in place in the end ofthe flared end 4.

A transparent glass disc 8 closes the end of the tube 1 opposite to theflared end 4. It will be seen that the disc 8 is slightly larger indiameter than the outside diameter of the tube 1 and acollar 9 providedwith a flange 10 is secured to the tube 1 in any suitable manner.

A second tubular member 11, the outside diameter being approximately thesame as the outer diameter of the tube 1, has the collar 12 securedthereto, the same being provided with a. flange 13. A ring like member14 rides upon the collars 9 and 12 and is provided on its innerperiphery and centrally from the ends with a reduced portion 15, thesame acting as a spacer to space the transparent disc of glass 8 fromthe glass disc 16 which will be made preferably of frosted glass. Thetube 11 intermediate its ends is provided with a flared portion 17- andthe reduced end portion. 18 having the electric light bulb 19 positionedtherein. The inner face of the members 17 and 18 may be silvered to actas a reflector to cast the rays of light from the bulb 19 forwardly.

As clearly indicated in Figs. 2 and 3, the tubel has positioned thereinthe convex lens a 20 carried by the discs 21 and 22 respectively. Thesaid discs are provided on their inner periphery with flared outwardlyextending. portions 23 and 34, respectively for clamping the outerdiameter of the lens 20 therebetween. The said discs are furtherprovided with the screws 24 for clamping the same together while thescrews 25, which are considerably longer than the screws 24, arethreaded through the disc 26 secured to the inner periphery of thetube 1. It will be clearly understood that upon adjustment of the screws25 the lens 20 will be moved toward or away from the glass disc 7consequently changing the focal point of the lens 20 in relation to theglass disc 7.

The disc 26 is provided centrally thereof with the aperture 27 and themirrors 28 are held between the disc 26 and the glass disc 8 and asclearly indicated in Fig. 4, the said mirrors form an equa-lateraltriangle, the reflecting faces of the same being upon the inside of thetriangle. A beveled gear 29 is pressed or' otherwise secured upon theouter periphery of the ring like member 14 and engages a pinion 30mounted upon the shaft 31, the same being carried in the bearings 32secured to the base 1. The shaft 31 is connected to the speed reducer 33which may be of standard construction, the same being operativelyconnected by means of the belt 34 to the electric motor 35, both themotor and the speed reducer being mounted upon the base 2. WVhen it isdesired to use the device as an advertising medium suitable pieces ofcolored glass or celluloid may be placed between the glass discs 8 and16 and the Whole device placed in an advantageous position in thedisplay window so that the glass disc 7 faces toward the outside of thewindow. The cord from the electric motor 35 will then be connected toany suitable source of current supply and the cord from the electriclight 19 also connected to a suitable source of current supply. When thecurrent is supplied to the motor the pinion 30 will be rotated at agreatly reduced speed, the same driving the gear 29 and since the gear,is secured to the ring like member 14 the same will be rotated causinga movement tovbe imparted to the pieces of colored glass or celluloidinserted between the discs 8 and 16.

The light from the bulb 19 will be directed forward illuminating thepieces of colored. glass and the mirrors 28 will pick up the reflectionof the same and cast it through the lens 20 onto the frosted discofglass 7., the same acting as a screen to catch the reflected image ofthe colored glass or celluloid pieces. Due to the arrangement of themirrors in the tube 1 the design which is cast upon the frosted glass 7will be of a kaleidoscopic nature and due to the rotation of the chamberin which the pieces of colored glass are placed and the consequentmovement of the said pieces in relation to each other an infinite numberof designs will be cast upon the screen 7 Although some of the designsmay repeat occasionally the series of designs will never be the samethus causing a continuous change of design both in shape and color whichwill attract the attention of the passer-by causing him to focus hisattention on the window in which the device isinstalled.

From the foregoing description it becomes evident that I have providedan advertising device which requires no manual operation and which willreflect a variety of desi s in shape and color upon a screen and furt erthat the device may be quickly and easily installed in a show window andwhich will draw the attention of the passer-by to the window.

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. In a device of the character described, a tubehaving a cylindrical portion and an outwardly flared cone like portion,a translucent plate at the larger end of the last named portion, a lensadjacent the point of connection between the cylindrical and flared endportions of the tube, means for adjusting the lens along the axis ofthetube, a system of mirrors in the said cylindrical portion of thetube, means for supporting the said tube from rotation, a transparentplate at the end of the cylindrical portion of the tube opposite theflared end, a translucent plate adjacent thereto providing a chamber forreceiving a series of colored objects therebetween, a rotatable elementhaving a portion extending between the said last named transparent andtranslucent plates for imparting movement to the obj ects,- and a secondtube having a cylindrical portion in alignment with the cylindricalportion of the first tube terminating adjacent the said second tube andhaving a recess, and a lamp in the said'recess.

2. In a device of the character described, a pair of stationary tubes inlongitudinal alignment, a series of mirrors arranged intriangulairelation in the forward tube of the pair, a glass cell formedof two spaced plates positioned between adjacent ends of the tube, arevoluble element having a portion extending to between the glasses bymeans of which colored objects may be changed in position, a lens in theforward tube, a translucent plate at the end of the tube beyond thelens, a lamp in the other tube, and means for revolving saidcontinuously revoluble element.

3. In a device of the character'described, a pair of stationary spacedtubes in longitudinal alignment, a series of mirrors arranged intriangular relation in the forward tube of the pair, a rotatable elementtherebetween providing a cell containing colored objects, one wall ofwhich is translucent and the other of which is transparent, means forrotating the said element to change the position of the colored objects,a lens in the forward tube, and a lamp in the other bymeans of whichlight is passed through the said cell and lens, and a translucentelement at the end of the forward tube of the pair on which the image isprojected.

In testimony whereof I sign this specification.
